SIFTER-TOP CLOSURE Specification of Letters Patent. I Patntd Sept. Illlt, 11915..

Application iiled November 17, 1913. Serial No. 801,384.

To all whomy it may concern.'

Be it known that I, ALFRED FRANKEN- BERG, a citizen of the United States, residing at Rockford, in the county of Winnebago and' State of Illinois, have invented certain new and useful Improvements in Sifter-Top Closures, of which the following is a speciication. i

rllhis invention relates t0 closures for containers adapted to contain pulverulent. or granular material, such as spices and similar substances, particularly When it is desired to sift or sprinkle the substances out ofthe container, or to quickly insert or remove large quantities thereof.

In my application for a patent, Serial No. 801,385, filed November 17 1913, I have shown and described a sifter-top closure so constructedrv that the sifting apertures may be quickly opened for sifting 1purposes, or the entire closure may be quic ly removed from the top of the container for the purpose of inserting or removing large quantities of the substance. The closure which I show and describe in the present application is so constructed that the sifter is adapted not only to open and closethe sifting apertures in the container top, but also to open and close a pouring opening. lVhen the sifter is in one position the container is closed, when in another position vthe sifting apertures are open and the pouring aperture is closed, and when in a third position, the pouring aperture is open and the sifter aperturesl are closed. Provision is also made for the removal of the entire closure when desired. I

In the accompanying drawings, Figure 1 is a perspective of the upper end of a container which embodies the features of my invention and `which shows the container in its closed condition. Fig'. 2 is a cross-section along the line 2-2 of Fig. 1. Figs. 3

tainer by any well-known or preferred means, for example by crimping the flange 4 upon the upper edges of the side 3 of the contalner. In the present embodiment, the horizontal portion 5 of the top 2 is depressed, as indicated in Fig. 2, so that the closure 8 does not project upward beyond the upper edges of the container walls 3. In the top 2 is a filling opening bounded by an upwardly extending liange 6 for receiving the closure, as indicated in Fig. 2.

The closure in this instance is composed of the oblong metallic member 8, and comprises the horizontal flat portion 9, the

downwardly extending flange 10, the out- Wardly extending horizontal ortion 11, and the guide ortion 12. The ange 6 of the top and ange 10 Vof the closure are so shaped that the closure ange fits snugly on the top flange, andv when pressed tightly thereon can be removed only by prying off the closure 8.

The sifter member 13 comprises the flat portion 14, the downwardly extending flanges 15, the guide flanges 16, and the operating handles 17. As indicatedmin Fig. 2, this memberis adapted to fit slidably on the closure 8, the guide ianges 16 coacting with the guides 12 of the closure, the shape of the different parts being such that the sifter can be slipped along the guides 12 by and the closure with apertures19 and 20.

When the sifter is in the position indicated by Fig. 1, the apertures are all closed. When the sifter is in the position indicated by Fig. 8, aperture 20 is closed, but apertures 18 register With apertures 19, so that the contents of the container may be sifted out through the registering apertures. When the sifter is in the positlon indicated by Fig. 7 apertures 19 are closed, but aperture 20 is open, so that the contained substance may be poured out; Also the entire closure 8, with the sifter, can be easily forced oft' from the top of the containery by slipping an instrument between the fianges 11 of the closure and the horizontal portion 5 of the top.

A stop 21 is provided on the closure against which one of the flanges 16 of the sifter comes in contact when the enlarged aperture 20 is to be opened. A stop 22 is provided on the closure against which the other iange 16 of the sifter comes in contact when the apertures 19 of the closure are to be opened. When the sifter is in a position intermediate of these two stops, the

v apertures ,are all closed, as indicated in Fig. 1. y

I claim as my invention: 1. In a. container, a top having'an opening i therethrough and having an upwardly exopening, an apertured closure having' a downwardly extending peripheral flange fitting snugly around said flange on the top, a plate overlying said closure, flanges-extending downwardly from the edges of said plate alongside said closure flange, and laterally extending portions on the lower edges of said flanges on the closure and plate, the said portions on one of the latter elements being bent around said portions on the other element.

3. In a container, a top having an elon- I gated opening therethrough and having an angular upwardly extending flange surrounding said opening, an apertured closure having a downwardly extending peripheral flange fitting snugly around said flange on the top, the opposite sides of the opening and closure and the corresponding portions of said flanges being straight and parallel, a plate overlying said closure, flanges extending downwardly from the edges of said plate along the opposite parallel sides of said closure flange, and laterally extending portions on the lower edges of said flanges on the closure and the plate respectively, the said portions on the closure being bent to overlie the portions on the plate, whereby to main-v .5U

tain the plate for rectilinear sliding movement on the closure.

4. A container having an elongated discharge opening, a closure therefor, said opening and closure having opposite parallel sides, a plate overlying said closure, interlocking means at the edges of the plate and the closure along said parallel sides adapted to maintain the plate for rectilinear sliding movement on the closure lengthwise of said opening, the closure having a pouring aperture therethrough at one end adapted to be closed by said plate, and one of the latter elements having a plurality of sifting apertures adapted to be closed by the other element.

5. A container having an elongated discharge opening with a surrounding angular flange, a closure for the opening having an angular peripheral flange to telescope with the first mentioned flange, the opposite sides of said opening and closure and the corresponding portions of said flanges being straight and parallel, a plate overlying said closure and having flanges at opposite edges lying along the straight portions of the closure flange, integral interlocking portions on the edges of said flanges on the closure and plate adapted to maintain said plate on the closure for rectilinear sliding movement lengthwise of said opening, the closure having a pouring aperture therethrough at one end arranged to be closed by said plate, and one of the latter elements having a plurality of sifting a ertures therethrough arranged to be closed y the other element.

In testimony whereof I affix my signature in presence of two witnesses.

ALFRED FRANKENBERG.
